Expected Behavior: Assets scale to 125% when directly on top of white areas. The animation is symmetrical. Refer to this animation.

Reality: The scaling is offset. Scaling is magnified and seems to be anchored at the bottom right corner.

I understand that the sample point has nothing to do with the actual layer position because the layers may not be comp sized and thus the coordinates don't match, but I'm not sure how to adjust the expression code.
